KAZAN, Russia — Authorities have lowered the speed limit to 70 kilometers per hour on a section of the R239 Kazan–Orenburg–Akbulaq highway leading into the Tatarstan capital, citing a pattern of traffic accidents. The restriction took effect Saturday, according to a statement from the Federal State Institution "Volgo-Vyatsk Uprador," the regional road administration overseen by Rosavtodor. The measure applies to the inbound lanes toward Kazan and is described as temporary.
